What is the average cost of developing a design for an Android mobile application?

Question

Android

I have never worked on designing for mobile applications before. A proposal has been received. Interested in how much, in principle, is allowed to demand for something like this.

Answer 1

As much as the buyer is willing to pay.

Answer 2

The price depends on the TK. This, by the way, is applicable not only for design and not only for Android. The average pricing policy can be viewed on freelance exchanges, or available vacancies on job search sites.
